The ASI1600MM-COOL monochrome astronomy camera is a new milestone for deep-sky imagers and comes at a fraction of the cost of far more expensive CCD cameras.

From the supply, the camera requires 12VDC @ 2A maximum. A Cooler Power LED shows when the cooler has sufficient power. There's also a large built-in heat sink which accounts for nearly 2\/3 of the camera's size. At the top of the camera, an advanced and efficient MagLev fan removes heat from the TEC and control electronics while keeping acoustic noise low.\u003c\/p\u003e\n\u003cp\u003eThe ASI1600MM-COOL has a robust and attractive CNC machined red-anodized aluminum body that stands up to heavy field use.
